Noninvasive EEG Recordings from Freely Moving Piglets Nora V. de Camp1,2, Silke Dietze1, Markus Klaßen3, Jürgen Bergeler1 1Institute of Animal Welfare, Animal Behavior and Laboratory Animal Science, Veterinary Medicine, Free University Berlin, 2Department of Biology, Behavioral Physiology, Humboldt University Berlin, 3Lehr- und Versuchsanstalt für Viehhaltung Hofgut Neumühle Here, we present a protocol to record telemetric electroencephalograms (EEGs) from freely moving piglets directly in the pigpen without the use of a sedative, making it possible to record typical EEG patterns during non-REM sleep, like spindle bursts.

Models for Preterm Cortical Development Using Non Invasive Clinical EEG Translational Neuroscience. 2017 | Pubmed ID: 29445543 The objective of this study was to evaluate the piglet and the mouse as model systems for preterm cortical development. According to the clinical context, we used non invasive EEG recordings. As a prerequisite, we developed miniaturized Ag/AgCl electrodes for full band EEG recordings in mice and verified that Urethane had no effect on EEG band power. Since mice are born with a "preterm" brain, we evaluated three age groups: P0/P1, P3/P4 and P13/P14. Our aim was to identify EEG patterns in the somatosensory cortex which are distinguishable between developmental stages and represent a physiologic brain development. In mice, we were able to find clear differences between age groups with a simple power analysis of EEG bands and also for phase locking and power spectral density. Interhemispheric coherence between corresponding regions can only be seen in two week old mice. The canolty maps for piglets as well as for mice show a clear PAC (phase amplitude coupling) pattern during development. From our data it can be concluded that analytic tools relying on network activity, as for example PAC (phase amplitude coupling) are best suited to extract basic EEG patterns of cortical development across species.
